Excluding syntax for folder synchronization in Unreal Commander

Unreal Commander is one of the best file manager software which is free of charge. When you want to synchronize two directories with considering only the specified file types, you will need to define filter string. “*.*” means to compare all files; “*.txt” means to compare also the text file. However, how can you compare any file except for “*.exe”?

Easy! Just add a “|” before the file types you want to exclude as show in the following picture.

Python initial script for Qtiplot

OK, even after reading the handbook a few times, it is not very clear which python file is the initial script for Qtiplot. It is important to know if you want to extend Qtiplot with python. After checking all the default python files in the Qtiplot installation path, I found qtiplotrc.py should be the one, although a smarter guy would have realized this from its name. You could import your own Python module in this startup file and enjoy them right after entering Qtiplot.

Origin绘图软件编程语言的几个层次

Origin是科学绘图和数值分析领域的一个十分强悍的商业软件。即使在开源流行的今天,Origin凭其优势仍可傲视群雄。当今的GUI软件,一个符合趋势的做法是支持脚本或者这样那样的编程扩展。这是由应用的多样化以及GUI程序天然的特点造成的:用户不再满足单一的使用流程,但是GUI程序的界面元素往往是开发时就订死的。Origin也不例外,它从6.0以后也在不断地朝支持编程的方向努力。否则,你看看它的对手们,Scilab, Octave, Qtiplot等好多好多,哪个不是天生就支持一门编程(脚本)语言的呢?

Change Pidgin theme on Windows

I’m using Pidgin v2.7 and Windows XP. I’ve tried most of the methods flying on the internet about changing themes for Pidgin, but none of them works. These include using the gtkthemeselector.exe. I noticed the latest Pidgin using a  “%APPDATA%\.purple\gtkrc-2.0″ to control the look and feel once the “GTK+ theme control” plugin is enabled. The contents of this file look very similar to the contents of the theme files under “c:\program files\common files\gtk\2.0\share\themes\***\gtk-2.0\gtkrc”. I tried to copy the contents of gtkrc file of the “Clearlooks-DarkLime” theme and pasted them to the “%APPDATA%\.purple\gtkrc-2.0″. After restarting Pidgin, I saw this :D

通过Samba在VirtualBox的guest和host间共享目录

Virtualbox支持客户机和宿主机之间共享目录,但是根据版本不同,会有些问题。例如对于3.1.x版本,windows XP host和Debian guest组合下,VBox自己的共享目录(写入)性能极差甚至报错(本人遇到)。其实,在客户机和宿主机之间共享文件的还有一些其他方式,例如可以通过ftp或samba,二者都支持所有操作系统下的共享,但是相比之下samba更具优点,因为在Windows和Linux下都可以把Samba共享目录映射为本地磁盘目录。
